Shaheed Diwas (Martyrs' Day) is observed annually across India on 23rd March to commemorate the martyrdom of three iconic revolutionaries: Bhagat Singh, Shivaram Rajguru, and Sukhdev Thapar, who were executed by the British government in 1931 for their pivotal role in India's freedom struggle. The day serves as a tribute to their courage, patriotism, and sacrifice, symbolizing the spirit of resistance against injustice.
